A CDCC notice group is considering whether Americans fully vaccinated with weakened immune system need a booster dose of a Covid vaccine after the data shows they are less likely to have antibodies against fight the disease and more likely to have a so-called rupture infection.
Immunosuppressed populations represent 44% of Covid emergency cases hospitalized in hospital: an infection in a fully vaccinated individual, according to a slide presented Thursday to the agency’s advisory committee on Meeting on immunization practices. The population segment, which includes patients with cancer, HIV or those who have had organ transplants, it represents only about 2.7% of the American adult population, the presentation said.
The Centers for The Advisory Committee on Disease Control and Prevention is also meeting to discuss safety profile of the Johnson & Johnson vaccine.
Immunocompromised people we are more risks becoming seriously ill with Covid and I am a higher risk of transmit the virus to family and friends, the agency said.
Studies suggest a third dose of the vaccine could help patients whose immune system does not respond as well to a first or second dose. four small studies cited by the CDC showed that 16% to 80% of people with the weakened immune system had no detectable antibodies to fight Covid after two hits.
Among immunosuppressed patients who had no detectable antibody response, 33% to 50% developed an antibody response after receiving an additional dose, according to the CDC.
“Emerging data suggest that an additional dose of COVID-19 vaccine in immunocompromised people improves the antibody response and increases its proportion who answer “, second one slide presented during the meeting.
The meeting comes as federal officials say booster doses of the vaccines for the general population they are not necessary in this moment.
The advice panel I can not recommend additional shots for anyone until the Food and Drug Administration concedes full approval of Covid vaccines or fine the emergency use authorizations.
Other countries, like France, they are already giving out third shot a people life with cancer or other immune disorders. The CDC group already said that more vulnerable Americans, such as the elderly people or transplanted, it can need one dose in more.
Some doctors are pushing for the United States a allow immunosuppressed populations to get an extra dose, according to Dr. Dan Barouch, an immunologist at Harvard Medical School who helped develop the J&J vaccine.
“The most difficult to vaccinate people are those who they are immunosuppressed, “he said, adding the first data shows a third shot can be safe and effective for those populations.
